LCD TV vs. LED TV

Despite having a different acronym, an LED TV is just a different type of LCD TV. The proper name would actually be “ LED-Backlit LCD TV”, but that’s too much of a mouthful for everyday conversation, so people generally refer to them as LED TVs, which can cause confusion.

Both types of TV make use of liquid crystal display (LCD) panel to control where light is displayed on your screen. These panels are typically composed of two sheets of polarized material  with a liquid crystal solution between them, so when an electric current passes through the liquid, it causes the crystals to align so that light can (or can’t) pass through. Think of each crystal as a shutter, either allowing light to pass through or blocking it.

An LED TV uses less power, provides a brighter display with better contrast, a thinner panel, and lesser heat dissipation than a conventional LCD TV. This is because an LED TV uses light-emitting diodes for backlighting as opposed to CCFLs (Cold Cathode Fluoresant Lamps) of conventional LCD TVs. The display of a LED TV is not a LED display, so more technically again, the correct name for it would be “LED-backlit LCD television”.
